RAILWAY-SWITCH.

Application filed March 3, 1915.

To all whom t may concern:

Be it known that I, CHARLES F. Rn'ror, a citizen of the United States of America, residing at Flint, in the county of Genesee and State of Michigan, have invented certain new and useful lmprovements in RailwayfSwitches, of which the following is a specification.

The present invention relates to improvements in railway switches, and is designed especially to provide a compact mechanism especially adapted for automatically operating street railway switches.

rlShe primary object of the invention is the provision of mechanism adapted to operate a switch, but which mechanism is Vactuated from a tappet or contact member carried by the railway car.

The invention consists in certain novel combinations and arrangements ofV parts of the operating mechanism as will be fully pointed out hereinafter and claimed.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles of the invention.

`Figure 1 is a plan view showing a box or casting with the lid removed, and the operating mechanism of the device disclosed therein. Fig. 2 is a transverse sectional view showing the box top and a wear plate thereon, and showing the slot construction of the wear plate and box top. Fig.- 3 is a longitudinal vertical sectional view of the box, taken at two different planes, for convenience of illustration. Fig. 4 is a view showing the actuating mechanism of the device carried by the railway car.

In the preferred embodiment of the in vention as illustrated in the drawing, I employ a metallic casting or box 1, which is preferably open at the upper end and provided with a top or cover 2, which is screwed or otherwise secured to the box 1. The box is provided with perforated lugs or flanges 3 3, by means of which it is secured to a suitable member inside the conduit or pit beneath the railway road bed. The box is designed to be bolted to the stationary member aforementioned, and stands with its operating parts in the position shown in Fig. 3.

llear the closed bottom end 4 of the box a transverse shaft 5 is located which ex- Specification of Letters Patent.

tends between two perforated lugs or bosses 6 6, each of which is integral with a side of the box 1, and this shaft 5 is supported in these two bosses 6 6. The shaft is placed in position through either of the two openings 7 -7 in the sides of the box 1, and these openings, after the shaft is in position, are closed by a pair of plugs 8.

rlhe shaft 5 is designed to support a rocking plate which comprises the sleeve 9 extending across the box, and a cam member or abutment 10 integral therewith. This abutment member is a plate having a shoulder 11 formed at its upper edge, and in Fig. 3 extensions 12 and 13 are provided which are adapted to co-act with the lugs 14 and 15 respectively. These lugs 14 and 15 are cast integral with, and project inwardly from, one of the side walls of the box, and are in the path of movement of the rocking plate. As seen in Fig. 3, the extension 12 of the rocking plate is in position over the lug 14, and it will be noted that the lugs 14 and 15 are situated at an angle so these extensions may rest squarely upon the lugs.

The normal position of the rocking plate is shown in the drawings, with the shoulder 11 in upright position, and the rocking plate is held in this position by means of a pair of coil springs 16 and 17 that are attached at 18 to an end wall of the box, and their other ends are attached to the arms 19 19 which project upwardly from the sleeve 9. These two springs hold the rocking plate in upright position as shown in Fig. 3.

The end of the rocking sleeve 9 opposite the rocking plate 10, is fashioned with an operating arm 20 which projects upwardly from the sleeve and has pivoted at its free end a horizontally arranged plunger bar 21. rlhe bar 21 is connected to arm 20 by a link 20 having the pivots 22 and 22. The plunger bar is supported in and is free to move through a pair of bearing sockets 23 28, and these socket members' 23 23 are each secured to the side wall of the box 1 by means of a screw as 24.

A link 25 pivoted at 26 to the under side of the plunger bar 21 ispivoted at 27 to the arm 28 of the bell crank lever 29, which is pivoted on a post 30 that rises vertically from the bottom of the box 1. ylhe other arm 31 of the bell crank lever is connected by a link 32 pivoted thereto at 33 to a push bolt 34, the connection with the push bolt being made by the pivot 35. This pushbolt, as clearly seen in Fig. .1, is adaptedto move in a direction at right angles to the plunger bar, and is supported in a perforated boss 36, a packing nut 37 being threaded into .the boss t0 support the push rod therein. The push rod has its end 3S projecting normally through a perforation 39-in one side of the box, and is adapted to move the vswitch tongue 40, indicated in dotted lines, Fig. 1.

The rocking plate 10, as clearly seen in Fig. 3, projects upwardly through a slot 41 in the top 2 of the box, and also through a slot 42 in a wear plate 43 which is fixed on vtop of theflid or top 2 of the box. A groove 44 extends approximately the length of the wear plate, and has a curved end wall 45. At each side of the groove 44 and slot 42 I locate a felt strip 46. Between these two strips the rocking plate 10 is designed to swing and be guided.

The above described mechanism is the operating device for the railway switch tongue 40, and this device is actuated by the mechanism illustrated in Fig. 4. This mechanism is carried on the car and comprises a socket member 4G secured in the ioor of the car and having a spring pressed foot trip 47. This trip is designed to pull a cable 48 passing over the pulley 49, and the cable has its other end Vattached to a bell crank lever 50 pivoted at 51 in a bracket 52, carried under the car, and in position where the tappet` spring pressed, and .is vintegral with the plunger. 54, which is connected by pivoted link 55 with the bell crank 50, and a spring wear plate 43. Tt will be readily seen by referring to Fig. 3, that when the tappet 53 enters the groove 44 at the left, it will travel to the right and encounter the shoulder 11 on the rock plate 10. The contact of the tappet with the shoulder, and the continued movementof the tappet causes the plate 10 to rock on the shaft 5, .and as the arm 2O also rocks, it will shove the plunger bar 21 to the right. This movement will cause the bell crank 29 to swinfr on its pivot 57, and the movement of the plunger bar will betransferred to the push bar. In this manner the push 4bar is shoved through the boss o-r bracket 36, and its end 38 being in contact with the switch tongue 40 will swing the Atongue on its pivot as readily understood.

The passage of the tappet 53 rides down the rock plate 10 until the plate encounters the lug 15, and by this time the tappet is freed from the shoulder of the plate. The two .springs 16 and 17 now retract the rocking the figures of drawing, but the device can equally well be applied for use on the railway track going in the opposite direction for the purpose of throwing the switch.

From the above description taken in'con- Y the pit ofthe switch mechanism, and which is vextremely simple inl its operation.
